Aiello from Pittsburgh

I am trying to help my mother do some research on her family tree.Her father's name was Dominic Aiello and was married for a couple of years to her mother Virginia.I mother was born on 8/1/1932 in Hazelwood, PA.When she was approx 3 years old her parents divorced and she wasnt able to make any contact with her father until 1970 when he traveled to CA for see her and our family. He returned to PA in June 1970 and passed away shortly thereafter.Sorry this is all the info I have on him at the present time.If anyone could provide any additional information it would be greatly appreciated.
